Lindy

Pros

• Agents can be built from a plain-English description or a template, without coding.
• Covers a lot of work out of the box: email triage, scheduling, meeting recording and notes, and phone calls.
• Computer use lets agents operate web apps that have no API connector.
• More than 1,500 integrations plus MCP support, including Gmail, Slack, HubSpot and Salesforce.
• SOC 2, GDPR and PIPEDA compliance, with a stated policy of not training models on customer data.

Cons

• Every action, including voice minutes, uses one credit pool, so costs are hard to predict and reviewers report credits running out quickly.
• Monthly credits do not roll over.
• Trustpilot reviewers complain about billing problems and slow or unreachable support.
• SSO, SCIM, audit logs and HIPAA are limited to the custom Enterprise plan.
• Third-party reviews describe some integrations, such as help desk connectors, as shallow.

Sierra

Pros

• Outcome-based billing means customers usually pay only for resolved conversations or other agreed results, not for each seat.
• Three build options cover both CX teams and engineers: the no-code Agent Studio, the code-first Agent SDK, and Ghostwriter for building agents from SOPs.
• One agent runs across chat, voice, SMS, WhatsApp, email and ChatGPT, keeping context between channels.
• Its list of compliance attestations is broad, covering SOC 2, ISO 27001, ISO 42001, HIPAA, PCI DSS and FedRAMP.
• It has a strong roster of enterprise customers, including SiriusXM, ADT, Rocket Mortgage and SoFi.

Cons

• There is no public pricing, and competitor estimates put annual contracts at about $150,000 or more.
• There is no self-serve or trial tier, so small teams cannot try it on their own.
• Implementation is largely vendor-led, which can make customers depend on Sierra's team for changes.
• There are few public reviews (7 on Gartner Peer Insights) to verify claims against.
• Some reviewers say voice quality still falls short of human level, and that complex telephony setups depend on how far the integration goes.
